Q-W=change in internal energy,closed system
1700-600=900j
this demonstrates the conservation energy as there is energy is no destroyed,instead energy is converted from one form to another and in this case the leftover energy of the system is the increase in internal energy of the system
Answer:
Explanation:
Let assume that cylinder has a radius of 0.01 meters. The Gauss Law has the following form:
The electric field considering the cylinder configuration that encloses the conducting cylinder is:
Where is the absolute permittivity.
Answer:
a. The average speed on her way to Grandmother's house is 48.08 mph
b. The average speed in the return trip is 50 mph.
Explanation:
The average speed (S) can be calculated as follows:
Where:
D: is the total distance
T: is the total time
a. To find the total distance in her way to Grandmother's house, we need to find the total time:
Where <em>v</em> is for velocity
Hence, the average speed on her way to Grandmother's house is:
b. Now, to calculate the average speed of the return trip we need to calculate the total time:
Therefore, the average speed of the return trip is:

Answer:
2.5m/s^2
Explanation:
to answer this question the best method would be to use SUVAT equations (attached)
here we have:
U= 0ms
v=25ms
t=10sec
a=?
the best equation to use in this instance is
v = u + at
substitute in the known values:
25=a10
25/10=a
2.5m/s^2 =a
